    What RPM do you run?

    I recently bought an 88 c15 which has a broken speedo. I have an aftermarket tach installed that has an adjustable marker arrow on it, so I have put the marker at the rpm the engine is running when I'm doing 65 on the highway, as a speed reference. The only thing is that I have a Turbo 400...

    Speedo Question

    I recently picked up an 88 c1500 and I've been trying to figure out why the speedo isn't working. After looking around here, I found a couple instances where people mention that the Turbo 400 tranny doesn't have a VSS that is needed to run the stock speedo. One of the PO swapped in the Turbo...

    Driveshaft problem

    So I recently picked up the 88 single cab short bed Chevy. A previous owner had installed a turbo 400 tranny, but didn't install the right driveshaft. Needless to say the driveshaft is too short and has caused damage to the tail cone of the transmission. Has anyone done this Turbo 400...
